The individual chromosomes of the cell become clearly visible within the nucleus with a light microscope as they condense from long, thin, wispy structures to thick structures, and they appear as a tangled jumble of paired, identical chromatids. By late prophase, the nuclear membrane disappears and all of the chromosomes are fully condensed. |  |  |  |  | Websites: |  |  |  |  |    |  |
